Document 313 -1 Flat Wire Power Inductor For Maxim MAX5051 Controller IC Designed for Maxim’s MAX5051 Power Supply Controller, the A9860‑B offers exceptional electrical performance. Flat wire windings offers extremely low DC resistance and high saturation current ratings. The flat core provides excellent heat dissipation. Core material Ferrite Terminations Tin-silver over copper Weight 11.4 g Ambient temperature –40°C to +85°C with (40°C rise) Irms current. Maximum part temperature +125°C (ambient + temp rise). Derating. Storage temperature Component: –40°C to +125°C. Tape and reel packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Failures in Time (FIT) / Mean Time Between Failures (MTBF) 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 Packaging 200/13″ reel; Plastic tape: 44 mm wide, 0.4 mm thick, 32 mm pocket spacing, 9.6 mm pocket depth PCB washing Tested to MIL-STD-202 Method 215 plus an additional aqueous wash.

Please specify termination and packaging codes: A9860-BD Packaging: D = 13″ machine-ready reel EIA-481 embossed plastic tape (200 per full reel). B = Less than full reel In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-D fixture in an Agilent/HP 4284A impedance analyzer. Isat4 (A) Irms5 (A) 20.0 15.0 63.0 3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD‑D test fixture. 4. DC current at which the inductance drops 10% (typ) from its value without current. Click for temperature derating information. 5. Current that causes a 40°C rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
